These are a sequence of powerpoint shows designed as an instant engagement task (rolling on screen as learners enter the room for immediate engagement with learning). Learners write down the the SI units for the named quantity. More able learners could provide SI units in terms of fundamental base units. They are essentially the same task (with rearranged slides) but get progressively more demanding (as the changeover of slide gets faster) as the numbers in brackets increase. Start the students with (1) and then as they get faster, use the more demanding versions

Key words: Universe, Galaxy, Solar system, Sun, planet, asteroid, constellation. This is a sort card activity and powerpoint show to support the task. It gets students thinking about objects in space. The powerpoint show comes in two forms, with or without the word constellation. The addition of the constellation card adds a real opportunity for cognitive conflict and helps iron out a preconception of what a constellation is.

This activity contains a powerpoint with graded questions & answers and matching pupil activity sheets, designed to be used at the end of a lesson and/or the start of the next lesson to review previous learning. The questions are based on the previous OCR 21st Century Science Specification unit P5, although could be used with other exam boards.\nClicking through the show reveals answers one a time. These reduce to A5 easily, the ideal size for most pupils. Please note grades are approximate.

This worksheet is useful for student to summarise information about the EM Spectrum, It can be used as an information gathering tool or to sum up key points about the spectrum. It could also be used for independent learning in school. It goes well with the activity EM Spectrum sort cards. There are three slightly different sheets that increase in demand from (1) to (3). This resource is part of a sequence with the following three other resources: This resource EM spectrum sort cards https://www.tes.com/teaching-resource/resource-6341302 IR remote control https://www.tes.com/teaching-resource/resource-12952897 UV Washing powder https://www.tes.com/teaching-resource/resource-12952892

This activity comprises of an interactive spreadsheet model that allows you to change the value in the yellow coloured cell to represent a percentage of noise added to a signal. It allows you to see what happens to both analogue and digital signals with the same amount of noise side by side. There is a worksheet to summarise the difference between the two kinds of signal and also an activity for pupils where they plot out signal plus noise by hand - ideal for a flipped learning approach where pupils do this in advance of the lesson before discussion in the lesson.

Keywords: p.d., voltage, potential difference, frequency, time period, time base, measurement This resource has a powerpoint show with worked examples of how to calculate p.d., frequency etc. using an oscilloscope. It is supported by graded intended learning outcomes and an independent learning task, which set as home learning has resulted in students being extremely creative.
